I will preface this by saying I have all the current updates, I am not rooted and do not have any third party apps installed.

This morning I noticed my phone would randomly reboot. I am not sure that it is even a complete reboot though. It was sitting on my desk at work and suddenly the Sprint splash screen that you see on startup would suddenly appear and then the UI would load up. I saw this happen about 4 times and I started to investigate. I checked to see if there were any apps misbehaving and couldn't find anything wrong.

While using my phone over the next couple of hours, the screen would randomly go black and the four buttons at the bottom would light up. The phone was completely locked up. I had to do a battery pull to get it to function again. This continued to happen then I would get a message saying that the rosie utility had stopped working and it asked me to either force close it or wait. Neither of these did any good and the phone would lock up. Time for another battery pull!

I then decided to try to do a factory reset including wiping the SD card. The phone locked up during the factory reset. I let it sit for half an hour then pulled the battery. It was still not reset and the phone exhibited the same strange behavior. I then tried another factory reset without wiping the SD card. Same result. Phone locked up, battery pulled, reset did not take effect.

Another hour of being pissed off and everything is magically started to work correctly on its own. The phone has been operating smoothly for the past ten hours.

Any insight as to what happened here? Did any of you in this thread experience anything like this?

I haven't had a problem today. Perhaps last night's factory reset or getting all the HTC software updates installed did it?

So you never had all of the OTA updates to begin with? Your initial post said you did the OTA updates and performed a factory reset. Factory resets do not wipe out OTA updates. So I'm trying to figure out how you installed the OTA updates twice?

My girlfriend works in IT and I don't think doing a factory reset on a phone is going to allow you to see what the IT department did to your phone. In my opinion, it will just erase everything they just did to your phone. Maybe EarlyMon or Novox can chime in on this. Correct me if I am wrong.

For example, Horadin did an excellent job posting whats on his phone and what isn't.
Its either apps, roaming, or battery. If all of those are good, take the phone back to the store. But try a factory reset before returning the phone to the store.

Horadin, I would suggest returning that brick for another phone. Every once and awhile a phone turns into a lemon. You seem to have done everything necessary for your phone to not reboot. Factory reset and updating user profile and PRL afterward. If that doesn't work, return that puppy.

Just one last thing for everyone. The phones will reboot for apps or the OS locking up. And if the battery is crapping out on you. And if you are using "Sprint Only" instead of "Automatic" for your mobile network selection. If the phone can't pick up a good network signal it confuses the hell out of itself and reboots. I don't know why.

Nope it is most likely an app you downloaded that is causing the issue, did it do this before you downloaded any apps, you you remember, I have gotten it a couple of times myself, but IMO I think it is app related.

So the Don finally upgraded from the Hero! Good job homie. I'm haunting this forum to see if I want to give my wife the evo and get one of these.

My buddy has had the same problem. I had him do a hard reset and it was Ok for a day and a half until he setup his email again...and it began rebooting in his pocket like before. His problem seems to be occurring due to his email setup in the Mail app.
Anyone else narrowed their problems down to this?

Mine did it quite a few times this afternoon, but it hasn't since 4:30pm (about 8 hours)... I'll wait another day and see how it is tomorrow. Then I'll try a hard reset. And if all that fails, I'll ask for a replacement. However, the problem I'm facing now is that the phone doesn't seem to be sleeping... ugh.

That's like what I experienced. Exact same symptoms--frequent lockups, and like you, the screen stayed black while buttons were lit and the device was totally unresponsive until I R&Red the battery.

Like you, it became stable, and I can't identify any factor that caused or cured this stability.

Really strange. My phone has been working perfectly for the past 24 hours now. I will just wait and see what happens with this one. If it acts up again I will exchange it . I just don't feel like dealing with it right now.

Had my first random reboot tonight. I was doing some web browsing, that arguably I could/should have been doing on my desktop that was 5 feet away. I really like to just lay about while browsing as opposed to seated at a desk in a chair with a rigid back on it.

I was on 3G with 2 fluctuating bars and full screen brightness for approximately 20 minutes. The phone got hot, nothing out of the ordinary, but eventually the net sort of locked up and the phone cycled power. I'm guessing it was an overheat of sorts. All I know is this better not become chronic, and it better not get frustrating.

I jumped from the Evo 4G because I was having overheating problems. Started out as a random reboot but became a habit eventually to where I couldn't use the phone for more than 10 minutes before it started endless power cycles.

I tend to have a low signal in my house for no good reason (with any phones), so maybe my 3G antenna are just in overdrive trying to grab the signal and hold onto it?

Also of note, my camera application wouldn't open earlier tonight. I tapped the widget and it opened to a black screen. Tried it twice then gave the phone re-boot and it worked fine. But that is a different issue.

I get random reboots on my phone as well. However, mine are exclusively related to being connected to my Wi-Fi. Also, it seems that it only happens when the phone is sleeping. For example, I can't think of a time that I was actively using it and it started a power cycle. However, multiple times I will bring it back from sleep to see that it has started or is starting a power cycle. Or I will wake it up to find that a power cycle has been completed (no recent apps listed).

My family recently got 4 3Ds and 3 of the 4 have had these type of problems everyday. Mine thankfully has not.

Sometimes a battery pull fixes it, sometimes multiple battery pulls will fix it. The people at the Sprint store gave a tip to wipe the phone and start over but holding down the lock button and the down-volume-key.

Fact of the matter is, this should not be happening at all. There is obviously a serious bug that needs to be addresses.

First timer here, I'm really disappointed mine is doing this as well. Not so much the black screen with bottom lights, but a shutdown with the HTC screen and Sprint Screen. This has happened multiple (10+) times in the 24 hrs I've had it.

So, I've had my new phone 3 days now and it's doing what everyone is describing in here...

I'll be using it and then for no reason at all, the screen just goes black and the lighted buttons at the bottom stay on. Sometimes a single battery pull will fix it and sometimes it takes two. This is happening now on average 1x per day.

The guy at the Sprint store said that less than 2% of the phones ever have a hardware issue and that it's usually (the 98%) a software issue.

This is totally unacceptable performance for a new phone!!! Wondering how many more days of this I will tolerate before I simply go back to Sprint and ask for a full refund.

I got my phone on Tuesday. As per above, had problems with lockups and random reboots. It got stable late Tuesday night and stayed stable until last night (Friday), when it rebooted itself for no reason. Then today, it locked up, with the hardware buttons unlit, and the battery and back of the phone were warm, so something was going on with the radio or CPU. Had to remove battery to get it to respond.

Despite warmness, battery wasn't depleted much.

How many random reboots/lockups per week did typical Evo 4G users get?

Same as described above.
Multiple reboots since I activated the phone 30 hours ago ( 10+ ).
Using programs as Camera, browser, Email, pretty much anything.
They give us 30 days I will just exchange it. Pronto

Ha just did it again. I bet there are programs not ready for gingerbread. I was getting similar stuff on my evo 4g.
I have installed
weatherbug
todo notes plus
e droid cell-pro
zedge
word of the day
I just flipped the sd card from my 4g to the 3d.
running BT, WiFi, GPS, 3G, Airrave
Exchange, mail, gmail

Just yesterday, my 3VO shut down while the I was listening to music and wouldn't power back on. I had to do a battery pull and plug it in before it would come back on. Again this morning, same deal, no juice and wouldn't power up. I'm going back to the store today for an off-center screen, and this just makes it that much easier.
